ATTACHMENT .FOR"KNIVES.

Specification of Letters Patent. Patented Aug,.5,1 913.

Application filed August 19, 1912.' serial no. 715, s27.

attachment being designed to ga e the thickness of the slices to be cut by a nife.

is the object of the present invention to provide a novel and improved means for adj ruling the gage relative to the knifeblade, and to this end the invention consists 'in a combination and arrangement of parts to be hereinafter described and claimed.

In the accompanying drawing forming a part of this specification, Figure 1 is an elevation showing the application of the invention- Fig. 2 is an-edge view. Fig. 3 isan enlarged cross-section on the line 3-3 of Fig. 2. Fi 4 is a cross-section showing a slight modi ation. I

Referring specifically to the drawing, 5 denotes the blade, and 6 the handle of the knife to which the gage attachment is applied. The gage, proper, isa flat blade 7 which is mounted parallel alongside the knife-blade and is'adjustable toward and from the same. Said gage blade is offset at 7 toward the knife blade, which makes it possible to cut a very thin slice.

The following attaching and adjusting means forthe gage-blade 7 are provided? Over the knife-blade 5 is slipped a U-shaped v member 8 having on one side a projecting stem 9 which is externally threaded by means ofa spiral groove 10. The stem has a threaded bore which is continued through the side of the member 8 from which the stem projects, and into which bore is screwed a set screw 11 of sufficient length to pass through the bore and have itsinner end engage one side of the blade 5 as shown in Fig. 3, whereby the member 8 is fastened to saidblade.

.In the modified structure shown in Fig. 4 the set screw 11 passes from the opposite side of the member 8 through the blade 5, and then into the boreof the stem 9.. On the stem 9 is mounted, to travel thereon, a nut 12 having a thread'to fit the groove 10, so

thatby turning the nut, it will be caused to' travel on the steni toward and f1'0l11',tlle knife-blade 5. The nut carries the gage- .b1ade'7. The inner end of the nut 12 is reduced in diameter and thinned out as indi-- cated at 13 on which portion the. gage blade 7 is mounted, said bladehaving an aperture through which the reduced .portion of the nut passes. The bla'de abuts on one side against a shoulder formed by the part 13,

and on the other side against a washer 14 mounted on said part and held in place by upsetting the latter against the washer, ,as

clearly shown in Fig. The gage-blade is" loose on the part 13 and the nut may. therearound as will be presently described. The butt-end of the gage-blade 7 is connected to M fore be rotated without. swinging said blade" a springlo which tends to swing said blade in a direction to bring its lower edge slightly below the cutting edge of the knifeblade 5. In the surface of the nut 1-2 are the nut until the spring finger is disengaged.

In operation, the spring finger 17 being in engagement wit-h one of the grooves 16, the knife 1s operated inthe ordinary manner to out a slice of bread, or anything else. j

The gage-blade 7 is adjusted so as to be spaced from the knife-blade 5 a distance corresponding to the desired thickness of the shoe to be out. already described, normally extends below the cutting edge of the knife-blade, and

therefore reaches the cutting board, or table As soon as the edge of thegage-blade reaches on which the loaf of bread rests, first.

the cutting board or table, the downward pressure on the knife-blade being continued, the gage-blade swings upward against the tension of the spring 15 and as said blade is coupled to the nut 12-, the latter turns on the stem 9. The groove 10 runs in such a direction that thisturning movement of the nut backs the same away from the knife-blade, and the gage-blade is therefore also carried away from the. slice which has been cut, and the latter is therefore not clamped between the blades but is at once released. Upon removing'the knife for a new cut, the spring 15 restores the gage-blade to its normal position.

In order to adjust the gage-blade? accordingto the desired thickness of the slice,

The gage-blade, as

the gage-blade has to be rotated to adjust it relative to the knife-blade.

I claim:

1. A gage attachment for knives comprising an attaching member, a threadedsteni carried by said member and extending outward from the knife, a nut screwed on the stem, a gage-blade loosely mounted on the nut, and means for fastening the gage-blade to the nut.

2. A gage attaclrment for knives comprising an attaching member, a threaded stem carried by said member and extending outward from the knife, a nut screwed on.

the stem and having a reduced portion forming a shoulder, a gage-blade loosely mounted 011 the reduced portion of the nut against the shoulder, a washer mounted on the reducedportion against the gage-blade, said reduced portion being upset to retain the Washer, and means for locking the gageblade to the nut.

copies at this patent may be obtained 3. A gage attachment for knives comprising an attaching member, a threaded stem 5 carried by said member and extending outward from the knife, a nut screwed on the stem and having a grooved surface, a gageblade carried by the nut, and a spring finger carried by, the gag'e blade and engageable' n with the grooves of the nut tocouple the gage-blade and the nut together.

i. A gage attachment for knives comprisingau attaching inembe ya stem carried by said member and extending outward from the knife, agageblade, a rotatable support for the gageblade mounted on the stem, on which support said gage blade is loosely mounted, means for adjusting the support toward or from the knife-blade when said support is. rotated, and means for coupling the gage-blade to the support.

5. A gage attachmentfor' knives comprising an attaching member, a threaded stein carried by said member, a gageblade, a support for the gage blade screwed; on the stem,

on which support said gage blade is loosely mounted, and means for coupling the gage blade to the" support. I
